IMPRovED TILE-CUTTING MACHINE.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern: v

Be it known that I, Osoan F. Moxronr, Vof Dear-V born, in the county of Wayne and State of Michigan, have invented a new and improved Tile-cutting Machine; Iand I do hereby declare that the following is-a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming a part of this specification. l

- This invention relates to improvements in machines for cutting the tile as it issues ii'om the tile-machine, in continuous form, into short sections, and oonsists in the application to the carrying-table, between two endless belts, of a tine wire or steel-plate cutter, stretched between au arm and a shaft, by which the shaft isfrevolved, so as to be revolved around the shaft and forced through the tile while moving along, the cutter being arranged to move with the tile while cutting, and back again after cutting, and the arm which supports the swinging end of the cutter being arranged to pass between the cut sections.

The invention also comprisesa carrying-table for passing the out pieces beyond the arm which snp ports the cutter suspended on the shaft, and held in position by a weight, so that the arm which carries `the cutter may pass around it.

The invention also comprises apparatus for moving the cutter along with the tile when cutting, and back again.

' Figure l is a plan viewvof my improved machine;

Figure 2 is a side elevation of the same; and

Figure 3 isa transverse section of the same.

'Similar letters of reference indicate corresponding parts.

A represents a suitable table or frame, on which is 'an endless belt, B, receiving the `tile in continuous form from the tile-making machine, and carrying it along to the cutter (l, which consists of a tine steel wire or other thin plate of hardened steel, as a watchspring, stretched between a shaft, D, or an arm, E, thereon, and the end'of au arm,-F, supported'in a line parallel with thershaft I), by a radial arm, G, mounted on the shaft.

Thisrshai't is arranged atl the side of the table,'par 'allelwith the carrying-belts, and the arm G moves across the path of the tile when the shaft is revolved, carrying the arm F down on the opposite side, causing the cutter to cut through the tile.

The speed of thecarrying-belt and the cutter-carrying arm is so arranged that the cutter makes-.one revolution while the tile is carried forward the length `of one section.

In order to cut the tile oti square, it is necessary Y that, while the cutter is in contact with the tile, it`

should move with it. For this reason the shaft D, which carries the arm G F, is mounted so as to slide iu its bearings, and a shifting-bar, H, is connected to it, for vmoving it forward and back,

This bar is pivoted at I to the bed-fiume, and has a long arm, K, extending along under the shaft, and

bent upward and backward, as shown at L M. This is moved'vdown by a cam, N, and up by a cam, O, attached to a pulley rim, P, attached to the arm G for the purpose, and also for imparting rotary motion to the shaft by a belt, Q.

The cam N, which strikes on the top of the arm K, forces it down, and thereby slides the vshaft D and cutter along with the tile. The adjustment of the cam is such that it strikes the lever at the time the cutter comes in contactwith the tile.

The cam O actslnpon the under side of the part M of the lever, and raises it, throwing the shaft and v cutter hack, immediately after the cn'tter passes below the tile. Y

After the sections are cut off, it. is necessary tocarry them away, also to separate them, to allow. the arm G to pass. Iior this purpose I provide another car-- rying-bclt, R, and cause it to run faster than the belt B does, the said belt being arranged to receive and draw a section away from the path of the arm, just previous to the passage of the said arm.

This arm passes a` little` more than the length of? one section from the path of the cutter, sc that there is always one section between them. This section must be supported on a table around which the arm F can pass. Therefore the said table S islsuspende'd from the shaft D, v'and is held in position while the cutting is done, by a bar, T, which catches into a weight, U, and is held in contact by a spring, V, and so arranged that it can be forced down toletthe arm pass, by a cam, IV, thereon.

IVhiIe the'arrn `is passing underr this weight, and the catch is disconnected, the table (is held in position by. the weight.

' ImmediatelyI after the arm I" passes under the weight, the catch T engages it again, and holds it firmly.

Tile said table is provided with rollers, to reduce the friction of the tile moving over it, which are forced along by the uncut tile on the b elt B. z

Other arrangement of means may be employed for moving the cutter forward and back in the direction ofthe movement ot' the tile, as described, and the shaft may be revolved by means other than the wheel P, in which case it might be dispensed with.

Having thus described my invention, That I claim as new, and desire to secure by Letters Patenaisl. The arrangement of the steel cutter C, con.
